2 Description The IS-ZW-TSTAT-300 programmable communicating thermostat operates via a high-quality, easy-to-use touch screen. To program or adjust your thermostat, simply touch your finger firmly to the screen. The screen will automatically light up and you will hear a beep. The screen will respond differently to different types of touches, so you may want to experiment by touching it different ways, finger, fingernail, etc. Do not use a sharp or metallic device; it will scratch the screen.

Touch and hold the arrow for fast time set (15 minute jumps). Touch the Day area to select the present day. The thermostat can be programmed to remind you when the HVAC system s air filter needs changing. Touch FILTER. The display will show the usage to date. Touch FILTER for over 3 seconds and the display will change to LIMIT. Touch arrows to set the desired usage limit before the filter alert comes on the Home screen. When this limit is reached, FILTER will display on the Home screen. You can set the limit from 0 to 999 days (default is 90 days). To reset the usage back to 0, touch the usage number; touching it again restores the displayed usage. This feature allows you to set the desired variance in temperature between the thermostat setting and the room temperature required before the heating or cooling system will turn on - from 0.5 to 2.0 F (0.25 to 1 C). For example, if SWING is set to 2.0 F and the thermostat is set to 70 F target temperature, the heat cycle will start when room temperature drops to 68 F. Similarly, the cooling system will start when the room temperature increases to 72 F. The HVAC then runs and will shut off at the target temperature. To set the feature, touch SWING. Touch the left/right arrows to set the SWING from 0.5 to 2.0 F. The HVAC will run more frequently at 0.5 F and less at 2.0 F. The default is 1.0 F. Touch the Home icon to return to the MENU screen. (This feature is used for two-stage normal or heat pump with aux only, the feature is not on screen for single stage.) The differential is the number of degrees between the room temperature and the target temperature at which the second stage will be used. The default is 2 F. Touch DIFF. Use the arrows to set the differential. We recommend 2 F for very cold climates and 4 F for warm climates. Your thermostat was accurately calibrated at the factory to ± 1 F of actual ambient temperature. You do have the option, however, to change the display temperature to match that of a previous thermostat, or to match another thermostat already in your home. The rage of change is from -6F to + 6 F or -3 C to +3 C. To change your thermostat calibration, touch CALIBRATE. Use the +/- to adjust the displayed temperature up or down as desired. The Delta Factor that appears on the screen will also automatically increase or decrease for each 0.5 (F or C) adjustment so you can see your change. The large display will show the modified temperature reading that will be displayed on the Home screen and used as the new room temperature. Touch to configure the unit to work with your HVAC system. Touch to turn the audible chirp sound on or off. Touch to toggle the temperature display scale between F and C. The thermostat has two lock modes. Touch the Unlock icon for 3 seconds; the unit will go into the Partial Lock mode (Lock icon with one bar). You can temporarily override the thermostat target temperature with the +/- buttons. 4 IS-ZW-TSTAT-300 Advanced Thermostat Operation Guide

5 For full lock, touch the Lock icon again for 5 seconds to go to Full Lock mode (Lock icon with two bars). No changes can be made. Once locked, the thermostat will respond just to mode and menu. To unlock, press the Menu button. Touch and hold the Lock icon for 5 seconds for two bars (if not there already). Then touch and hold the Lock icon for another 5 seconds. Each 5-second touch and hold must be separate. Home icon Return to the Home screen. Program screen Press the Prog button to display the Program screen.
